Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage pipeline engineering, and mainly relates to a tool for opening water supply valves in underground well chambers. Background Technology

[0002] In urban underground pipe networks, various valve wells play a crucial role in fluid control. Due to the damp and dark environment inside these wells, valves are constantly exposed to corrosive conditions. Furthermore, the narrow and poorly ventilated spaces within these wells in urban underground pipe networks frequently lead to difficulties in opening and closing the valves. Traditional operating methods require personnel to enter the wells, posing multiple safety risks.

[0003] 1. Risk of accidents in confined spaces: The well chamber is a closed space, which may be subject to oxygen deficiency (oxygen concentration below 19.5%) and accumulation of toxic and harmful gases (such as hydrogen sulfide and methane), which may easily lead to safety accidents such as poisoning and suffocation.

[0004] 2. Difficulties in working with water: There is often water accumulation or damp environment in the well. Valves and operating parts are prone to rust and jamming. Operators need to operate in mud and water. The working conditions are harsh and secondary accidents such as slipping and electric shock are likely to occur.

[0005] 3. Inconvenient operation and low efficiency: The confined space downhole makes effective operation difficult. For severely jammed valves, it is difficult to apply sufficient torque downhole, often requiring multiple attempts to go up and down the well, resulting in extremely low work efficiency.

[0006] 4. Difficulty in emergency rescue: Once an accident occurs underground, rescue is difficult. Due to the size of the wellhead and the environment, rapid and effective rescue is often difficult to implement. Utility Model Content

[0007] In view of this, the present invention proposes a tool for opening underground well water supply valves, which is used for portable ground operation of underground well valves. The tool is characterized by comprising: a rotating handle, an extended transmission rod, and a connector.

[0008] The rotating handle is connected to the connector via the extended transmission rod;

[0009] The connector is used to insert into the water supply valve and is fixed to the water supply valve switch;

[0010] By rotating the handle, the extended transmission rod drives the connector to rotate, thus opening and closing the water supply valve.

[0011] Furthermore, the rotating handle is a rod-shaped structure, and the rotating handle includes multiple handles, with at least two handles.

[0012] Furthermore, the rotating handle is arranged vertically and symmetrically about the extended transmission rod, and the center of the rotating handle is fixedly connected to one end of the extended transmission rod.

[0013] Furthermore, the connector includes a connecting connector and two adapter connectors, wherein the connecting connector is fixedly connected to the adapter connectors.

[0014] Furthermore, the connector has an inverted T-shaped structure, including a plug and two fixed ends, with the plug of the connector extending into the tube at the other end of the extended transmission rod.

[0015] Furthermore, the tube of the extended transmission rod and the connector of the connecting joint have corresponding insertion holes.

[0016] Furthermore, a screw is inserted into the socket to fix the extended transmission rod to the connector.

[0017] Furthermore, the two adapters are respectively fixed to the two fixed ends of the "inverted T-shape" of the connecting joint.

[0018] Furthermore, the two adapters are arranged symmetrically with respect to the connecting connector.

[0019] Furthermore, the two adapter joints are oriented in the opposite direction to the extended transmission rod, and are located on the upper and lower sides of the connecting joint, respectively.

[0020] The beneficial effects of this utility model are as follows: The extended transmission rod design avoids the risk of operators entering the underground well, effectively improving construction safety. It also eliminates the tedious ventilation, testing, and protective preparation time before entering the well, avoiding repeated attempts and significantly shortening the time for each operation, thus improving work efficiency. Through leverage, it reduces labor and maintenance costs, requiring less effort and eliminating the need for multiple personnel, while also reducing reliance on expensive large-scale ventilation equipment, continuous gas detectors, and full-body protective clothing. By reducing the need for forceful valve operation, it extends the valve's service life. Utilizing the combined design of the extended transmission rod and modular adapter head, this device can be adapted to different valve models, greatly improving equipment utilization.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other implementations obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. In the various drawings, the same elements are represented by the same or similar reference numerals, and for clarity, the various parts in the drawings are not drawn to scale.

[0028] See Figure 1-4 As shown, this utility model proposes a portable ground operation method for underground well chamber valves, characterized by comprising: a rotating handle 1, an extended transmission rod 2, and a connector 3; the rotating handle 1 is connected to the connector 3 via the extended transmission rod 2; the connector 3 is used to insert into a water supply valve and is fixed to the water supply valve switch; by rotating the rotating handle 1, the extended transmission rod 2 drives the connector 3 to rotate together, thereby realizing the opening and closing of the water supply valve. In this embodiment, one end of the extended transmission rod 2 is fixedly connected to the rotating handle, and the other end is movably connected to the connector 3, allowing for the replacement of a suitable connector 3 according to the size of the underground well chamber valve.

[0029] Specifically, see Figure 1As shown, the rotating handle 1 is a rod-shaped structure, comprising multiple handles 11, with at least two handles 11. The rotating handles 1 are arranged perpendicularly and symmetrically about the extended transmission rod 2, and the center of the rotating handle 1 is fixedly connected to one end of the extended transmission rod 2. In this embodiment, there are two handles 11, arranged parallel to each other at 180°. The extended transmission rod 2 is fixed to the center of the handle 11 connecting rod, and is perpendicular to the handle 11. Preferably, the extended transmission rod has a certain length to ensure that when the device is inserted into the underground well valve to be rotated, it can be higher than the underground well opening, ensuring that the workers' working environment is above ground level. Furthermore, the length of the rotating handle is much greater than the width of the connector, forming a lever during the use of the device, achieving a labor-saving purpose in opening the underground well valve.

[0030] See Figure 2 , 3 As shown, specifically, the connector 3 includes a connecting connector 31 and two adapter connectors 32, with the connecting connector 31 and the adapter connectors 32 fixedly connected. The connecting connector 31 has an inverted T-shaped structure, including a plug 311 and two fixed ends 312. The plug 311 of the connecting connector 31 extends into the tube 21 at the other end of the extended transmission rod 2. Specifically, the two adapter connectors 32 are respectively fixed to the two fixed ends 312 of the inverted T-shape of the connecting connector 31. The two adapter connectors 32 are symmetrically arranged with the connecting connector 31 as the center. As the direction of the two adapter connectors 32 is opposite to the direction of the extended transmission rod 2, the extended transmission rod 2 and the adapter connectors 32 are located on the upper and lower sides of the connecting connector 31, respectively. In this embodiment, the two adapter connectors 32 are fixed to both ends of the connecting connector 311, and the adapter connectors 32 are flush with the plug 311.

[0031] See Figure 4As shown, preferably, the tube 21 of the extended transmission rod 2 and the plug 311 of the connecting joint 31 have corresponding insertion holes 4; a screw 5 is inserted into the insertion hole 4 to fix the extended transmission rod and the joint, and the joint 3 is inserted into the extended transmission rod 2. In this embodiment, the plug 311 of the connecting joint 31 is inserted into the tube 21 of the extended transmission rod 2, and the outer diameter of the plug 311 is slightly smaller than the inner diameter of the tube 21; the tube 21 and the plug connection part have insertion holes 5 on both the front and back sides, and the screw 4 passes through the insertion hole 5 to fix the extended transmission rod 2 and the joint 3, preventing the joint 3 from moving or slipping; and facilitating the replacement of the joint 3 to adapt to underground well chamber valves of different sizes. Preferably, the plug 311 has insertion holes 4 on both the front and back sides, and the distance between the two adapter joints is 220mm, serving as the basic adapter joint; the devices are all coated with corrosion-resistant materials to prevent rust liquid corrosion and extend the service life of the devices.

[0032] In use, the adapter plug 32 of the plug 3 is inserted into the underground well valve that needs to be opened or closed; the handle 1, the extended transmission rod 2 and the plug 3 form a simple lever; by rotating the handle 1, the extended transmission rod 2 drives the plug 3 to rotate, thereby realizing the opening or closing of the valve.

[0033] The beneficial effects of this utility model are as follows:

[0034] Enhanced safety: The core value of this utility model lies in completely eliminating the need for operators to enter the valve well, thereby fundamentally preventing personal injury accidents caused by suffocation, poisoning, drowning, electric shock, etc.; at the same time, it avoids the complex rescue risks that follow, providing municipal operation and maintenance personnel with an inherently safe way of working.

[0035] Improved operational efficiency: It eliminates the tedious ventilation, testing, and protective preparation time before going down into the well, achieving "ready to use immediately". Even for severely corroded valves, a huge torque can be easily applied on the ground to open or close them, avoiding repeated attempts to go down into the well and significantly shortening the time for a single operation.

[0036] Reduced labor costs: No need for multiple people to cooperate, such as surface monitoring + downhole operation, usually 1-2 people can complete the operation; Reduced protection investment: Reduced reliance on expensive large ventilation equipment, continuous gas detectors and full-body protective clothing, etc.; Reduced maintenance costs: By reducing violent operation of valves, the service life of the valves themselves is extended; The rust-proof design of the device also reduces its own maintenance frequency.

[0037] Excellent versatility and adaptability: Through the combination design of extended transmission rod and modular adapter head, one set of equipment can cover most valve wells of different depths, valve types and operating head sizes, greatly improving the utilization rate of the equipment.
